After a long and difficult construction process, Answers In Genesis and The Creation Museum president and CEO Ken Ham finally completed his Ark Encounter theme park in Kentucky, centered around a 510-replica of Noah's Ark. The grand opening was last week. Ham's distinguished guest? TV personality Bill Nye "The Science Guy," who has previously debated Ham hotly over creation versus evolution.

Surprisingly, evolution-defender Nye accepted Ham's invitation and got a personal tour as other visitors and reporters crowded around, according to Answers In Genesis.

"Our presence there together created quite a stir with other Ark guests," Ham wrote.

"As we walked through the Ark, we had a very passionate discussion. It was like the debate all over again but more intense at times," he wrote, before adding, "Though it did get tense due to our differences in worldviews, it was an amicable visit."

Ham said the focus of their discussion was on Flood geology and the Ice Age in relation to the age of the earth. But Ham took the opportunity to say even more.

"During [Nye's] visit I was able to personally share the Gospel with him very clearly. On the first deck, I asked him, before a crowd of people including many young people, if I could pray with him and was able to pray for him there. Our prayer is that what he saw will have an impact on him and that he will be drawn to the gospel of Jesus Christ that is clearly presented at the Ark."

The Christian Post reports that Nye had previously said, "If [Ham] builds that ark, it's my strong opinion, it's bad for the commonwealth of Kentucky and bad for scientists based in Kentucky and bad for the U.S. And I'm not joking, bad for the world."
